@Nick-Carthew Hi Nick, yep I was referencing to the MRA RouteXperts. I can't remember which route they were on - if I come across the tracks/ routes I will let you know.
One I remember was at a watercrossing before Minehead next to Allerford packhorse bridge. Waterlevels were too high for me to cross. But that could be the result of rain falling down by the buckets.
And another one was near a castle ruin - do no remember which one - but am sure will come acoss it when editting filmmaterial. Will let you know when I find it.
Beside mentioning the obstacles eg only possible for 2 wheels - it would be very helpful if that part of the track somehow could could be marked (specific colour?) so that beforehand the route, for that part, could be adapted to to 3 or more wheels.
Do not get me wong I thoroughly enjoyed the routes made during my trip around Southern England. Did some very steep roads (33%/33% descent/ ascend), as well as mega narrow tracks with mud/ grass in middle _ I would not have found on my own.
